Launch Abort Motor on NASA's New Spaceship Passes Test

WASHINGTON ? Alliant Techsystems (ATK) performed a
successful ground test Dec. 14 of a full-scale attitude control motor for the
launch abort system of NASA?s planned Orion Crew Exploration Vehicle, according
to company officials.

Bart Olson, vice president and general manager for ATK
Tactical Propulsion and Controls, said the test, performed at the company?s
facility in Elkton, Md., is a major accomplishment for the Launch
Abort System team, led by Orbital Sciences Corp. of Dulles, Va., and Orion
prime contractor Lockheed Martin of Denver.

Minneapolis-based ATK is supplying two of the Launch Abort
System?s three propulsion systems.

?This successful milestone brings Constellation
another step closer to flight-ready status and demonstrates progress toward
improved flight safety for astronauts that is at the core of Constellation
Program success,? Olson said in a Dec. 16 news release. Olson was referring to
NASA?s five-year-old shuttle replacement effort, Constellation, which includes
the Orion crew capsule and its Ares 1 launcher.

The administration of U.S. President Barack Obama is
currently mulling alternatives to Constellation, including scenarios that would
scrap Ares 1 in favor of outsourcing space operations in low Earth orbit to the
private sector. Although Obama and NASA Administrator Charles Bolden met Dec.
16 to discuss various options for the agency?s human spaceflight activities and
investments, details of a forthcoming presidential decision are not expected
until the White House submits the 2011 federal budget request to Congress in
February.

The Dec. 14 attitude control motor test is good news for Orion
as Lockheed Martin gears up for the capsule?s first pad-abort test in late
January or early February at White Sands Missile Range, N.M. The 90-second
flight test, originally slated for September 2008, has been delayed several
times, due in part to technical problems associated with the Launch Abort
System?s attitude control motor.

ATK said early indications are that the Dec. 14 test, dubbed
?Demonstration Motor 1? was successful and engineers are now analyzing the
detailed results. This was the sixth in a series of ground tests of Orion?s
attitude control motor system, validating that the thruster system performs as
designed, according to the news release.

Orion?s attitude control motor provides steering for the
Orion launch abort system, which is designed to safely lift and steer the Orion
crew capsule away from Ares
1 in the event of an emergency.
